+=======================================================================
+---      Release of Lynx2-6FM as Lynx v2.7 (February 15, 1997)      ---
+=======================================================================
+1997-02-15
+* Release of Lynx2-6FM as Lynx v2.7. - FM
+* Included -Ae when compiling the Implementation modules for the snake3
+  target. - FM
+1997-02-14
+* Mods to issue an alert about a BASE tag not having an absolute URL only
+  once per document. - FM
+* Added code for appending LYNX_SIG_FILE to email messages as well as to
+  news posts or followups, and updated the Users Guide accordingly. - FM
+* Updated build-slang.com. - FM
+1997-02-12
+* Fixed some problems in the code for using a hookless Lynx image with
+  snew_proxy, snewspost_proxy, and snewsreply_proxy set to
+  "nntp://host:port/" so that it uses Tom Zerucha's (tz@execpc.com)
+  daemon which handles the SSL communications on behalf of the Lynx
+  image.  Also polished up all of the news gateway code, and added
+  comments for the benefit of new developers. - FM
+* Added an ECGOTO command mapped by default to 'G', complementary to the
+  GOTO command (default 'g'), to edit the current document's URL and then
+  go to it.  Using case-sensitive letters with different command definitions
+  ensures that both will appear with their brief explanations in the 'k'eymap
+  listing.  For ECGOTO, Control-G, failure to modify the URL, or complete
+  deletion of it, all act as a cancel.  If the current document has POST
+  content associated with it, a warning will be issued before offering the
+  URL to edit.  The POST content is retained if the modification merely
+  involves a change in fragment for the URL.  Otherwise, the modified URL
+  (if it has an http scheme) will be submitted with method GET and no POST
+  content.  If the ECGOTO command is not cancelled, or not simply a fragment
+  change, the modified URL will be added to the 'g'oto buffer, and can be
+  re-accessed, to edit further, via the GOTO command.  See the updated online
+  'h'elp for more information. - FM
+1997-02-10
+* Amplified the comments concerning deletion of prototypes for MultiNet
+  socket library functions as they get added to MultiNet's own headers
+  in newer versions of it's socket library. - FM
+* Added a missing fclose() in post_article() of HTNews.c, and added code
+  to delete the temporary file there, so it's gone as soon as we're done
+  with it. - FM
+02-09-97
+* Enhanced the Set-Cookie header parser to handle values that contain
+  spaces but were not enclosed in double-quotes, and to use such
+  quoting or not when sending Cookie headers, depending on whether
+  this was done in the Set-Cookie header.  Also added anti-crash
+  checks should the parser's efforts to handle both historical (a.k.a.
+  original Netscape) cookies and Version 1 cookies go awry (does deal
+  successfully now with all the cookies which had been reported as
+  problematic). - FM
+* Mods of the screen handling in LYNews.c for cleaning up any screen
+  trash created by the external editor. - FM
+* Tracked down an uninitialized pointer in LYNews.c that probably was
+  behind reports of crashes when posting to newsgroups. - FM
+* Plugged a memory leak in LYMainLoop.c. - TJC
+* Added posting ability to the news gateway, in lieu of the previous,
+  variably reliable, use of a spawned news client for posting.  The
+  news, nntp, and snews URLs now all return links for posting new
+  messages or followups (replies) to the server from which a newsgroup
+  listing or news article was retrieved, unless the server indicates
+  that it does not accept posts from the site at which Lynx is running.
+  See the updated INSTALLATION, userdefs.h, and lynx.cfg files, the
+  "USENET News posting" section of the Users Guide, and "Supported URLs"
+  page of the online 'h'elp for more information.
+* Fixed typo for e-dieresis in the KOI8-R charset. - AJF
+* Replaced an inappropriate _user_message() call in HTConfirmCookie()
+  of HTAlert.c with a _statusline() call.  The original code could
+  cause crashes with some cookie values. - FM
+02-06-97
+* Added support for both hex escaped and unescaped white characters
+  in lynxexec and lynxprog URLs.  Normally, Lynx strips out any white
+  characters that are not hex escaped in attribute values that are
+  to be resolved as URLs, on the assumption that they were derived
+  from wrapping in the markup.  Any serial white characters in
+  lynxexec and lynxprog URLs are condensed to one space (' '), and
+  any lead or trailing white characters are trimmed.  Note that we
+  still require hex escaping of spaces in mailto URLs, e.g,
+  HREF="mailto:lynx-dev@sig.net%20(I%20found%20a%20bug.)". - FM
+* Removed the 'e' switch from tar commands in LYLocal.c for greater
+  portability across all supported Unix flavors. - FM
+* Expanded the information in the PROBLEMS file on how to deal with
+  DECC and MultiNet header incompatibilites for different combinations
+  of the VMS compiler and socket library versions. - FM
+* Added TRACE message of the edit command created for the system()
+  call in LYEdit.c. - LWV
+* Fixed a typo in the userdefs.h comments. - NHE 
+02-04-97
+* Mod in LYMainLoop.c to bypass mailing "not found" messages when
+  MAIL_SYSTEM_ERROR_LOGGING was set TRUE (which it should NOT be,
+  indescriminately) if the document's owner is the lynx-dev list. - FM
+* Added crash protection checks for the actual presence of anchors
+  in all HText structure anchor scans in GridText.c, based on a crash
+  report and suggested fix for one of them from Jonathan Sergent
+  (sergent@hillres55-129.cc.purdue.edu). - FM
+* Eliminated the typecast for ttytype (apparently varies across flavors,
+  and each flavor should know it's own typing; we'll see) in LYCurses.c,
+  and moved VMS system definitions with non-ANSI conformant tokens to a
+  separate header for VMS (LYVMSdef.h). - BL
+* Made the description of HISTORY in the 'k'eymap page more clear that
+  it invokes a list of the "suspended" documents currently held in the
+  history stack. - DC
+* Typo fixes in the help files and lynx.cfg. - LWV
+02-03-97
+* Today's distribution is a pre-release of v2.7.  The projected official
+  release date is 02-15-97.  All header, help and documentation files,
+  and the top directory name, have been updated for v2.7. - FM
+* Made xli, which is freeware, the default XLOADIMAGE_COMMAND for Unix
+  in userdefs.h (still xv on VMS, since its port is freeware), and
+  expanded the "self-documentation" to indicate where to get this
+  freeware.  Added XLOADIMAGE_COMMAND as a configuration symbol in
+  lynx.cfg, so that the compilation default can be overridden on
+  systems which have and prefer xv (all users can override the default
+  mappings for image helper apps via their mailcap files) - FM
+* Added a -base command line switch which can be used with -source or
+  -mime_header to prepend the request URL as a comment, and a BASE tag
+  (which may or may not be the same as the request URL, depending on
+  HTTP/1.1 headers) for text/html documents, equivalent to the prepend
+  kludge for 'd'ownloads (see 09-20-96 mods). - FM
+* Added a check for an "ORGANIZATION" environment variable for inclusion
+  as a news post header on Unix (all system logicals intended for news
+  post headers automatically are included on VMS), and a sleep() before
+  restoring curses mode after the post, to allow reading of any error
+  messages from the news software. - FM
+* Fixed bug which yielded a "[LINK]" instead of "[INLINE]" pseduo-ALT
+  for ALT-less IMG tags used as the content for NAME-ed Anchors without
+  an HREF. - FM
+* Portability tweaks for the mini inews utility. - FM
+* Fixed an old and irrelevant typo in HTWriter.c. - JS
+01-29-97
+* Added more REL tokens that are acceptable for banner links. - FM
+* Ifdef'ed the standard foo_PATH definitions for FreeBSD at the bottom of
+  userdefs.h, based on a patch from AAC, and assuming they also apply for
+  NetBSD, BSDI, and Linux (we'll see 8-). - FM
+* Added make freebsd-slang target. - AAC
+01-28-97
+* Mods of LYSetCookie() to ensure setting of 443 as the default port for
+  https URLs, and force the secure flag on for https URLs whether or not
+  the Set-Cookie header had a secure parameter (too many Version 0
+  cookies don't, when they should). - FM
+* Removed -ltermcap from make for all ncurses targets. - FM
+* Tweaks of make for FreeBSD. - AAC
+* Use SLtt_get_screen_size() instead of the apparently less portable
+  code for slang in size_change() of LYUtils.c. - JED
+01-27-97
+* Made ALT a synonym for VALUE in INPUTs with TYPE="image" to cooperate
+  with well-intentioned (though misinformed) providers who use ALT instead
+  of VALUE for the benefit of text clients or GUIs with image handling
+  turned off. - FM
+* Modified the code for submission of form content with TYPE="image" NAME-ed
+  INPUTs that have a VALUE (or ALT) to "fake" a 0,0 coordinate pair, as when
+  a VALUE (or ALT) is absent, instead of sending a single name=value pair.
+  Requests that using a name=value pair in such cases to indicate that the
+  submission was from a text client or GUI with image handling turned off
+  be included in the HTML specifications keep falling on deaf ears, so we
+  may as well "fake" something closer to what the CGI scripts are expecting,
+  and hope that the script interprets 0,0 as an indicator that the user did
+  not see the image and make a conscious choice within it.
+* Added code to offer a link for the SRC of the image in INPUTs with
+  TYPE="image", distinct from the submit button, when clickable images
+  is on. - FM
+* Updated the "HTML Forms" section of the Users Guide. - FM
+* Fixed a typo in the parsing of Cache-Control MIME headers and META
+  directives. - FM
+01-25-97
+* Updated lynx_help_main.html, about_lynx.html and about_lynx-dev.html. - FM
+* Mods to indicate a toolbar by a '#' preceding its first link when the
+  toolbar is being displayed, and to indicate the availability of a toolbar
+  by a '#' in the top, left-hand corner of the screen when the toolbar is
+  not being displayed.  Added explanation of this in the online 'h'elp. - FM
+* Indicate the 'allow' setting (always, never, or via prompt) for each
+  domain in the Cookie Jar Page. - AK
+* Don't delete cookie-less domains silently during garbage collections if
+  they have their 'allow' set to always or never. - AK & FM
+* Added ability to change the 'allow' settings for domains via the Cookie
+  Jar Page. - FM
+* Added basic protection against "denial of service attacks" by limiting
+  a domain to 50 cookies, the total number of stored cookies to 500, and
+  the maximum processed size of a cookie to 4096 bytes. - FM
+* SGML escape any ampersands or angle brackets in the cookie names, values,
+  parameters, and comments when creating the HTML stream for the Cookie
+  Jar Page, and only include entries for comments if they were present in
+  the servers' Set-Cookie headers. - FM 
+* Updated the online 'h'elp for cookies. - FM
+* Removed -DNO_KEYPAD from all ncurses targets in the Makefile. - FM
+01-23-97
+* Added a "Lynx State Management (Me want cookie!)" section to the Lynx
+  Users Guide, and a cross-linked cookie_help.html file for the Cookie
+  Jar Page. - FM
+* Added prompting for whether to show the body of a 401 status reply or
+  simply return to the current document when an activated link requires
+  authentication via a username and password, and the user has none for
+  that realm, or forgot them. - FM
+01-22-97
+* Added handling of expires attribute values in Version 0 (a.k.a. Netscape)
+  Set-Cookie MIME headers or META tags, and added "Maximum Gobble Date"
+  entries in the Cookie Jar Page which indicate the maximum intended age
+  for each cookie based on the Version 0 expires or Version 1 max-age
+  attribute values. - FM 
+* Added an LYmktime() function in LYUtils.c which accepts strings in the
+  format "Day, dd-Mon-yy hh:mm:ss GMT" or "Day, dd Mon yyyy hh:mm:ss GMT",
+  parses and converts them to time_t format (seconds since 00:00:00 Jan 1
+  1970), and returns the time_t value, or zero if the date is in the
+  past.  It is used for handling Expires headers or attribute values. - FM
+* Added parsing of Cache-Control and Expires MIME headers and META tags
+  sufficient to determine whether the no_cache element should be set in
+  the document's structures. - FM
+* Eliminated the "; $Path=foo; $Domain=blah" attr=value pairs when sending
+  Version 0 (a.k.a. Netscape) cookies in request headers, because too may
+  CGI scripts in the real world have brain-dead parsers and fail when they
+  are included. - FM
+* Added handling of Set-Cookie directives in META tags. - AK
+01-20-97
+* Added confirmation prompts for deletions from the Cookie Jar, expanded
+  the garbage collecting for expired cookies, debugged and implemented the
+  code for security checks based on lead and embedded dots in domain values
+  and host prefixes as described in Section 4.3.2 of the -05 State Management
+  draft, added requirement for https URLs (direct, or via proxy) to include
+  cookies which have the secure flag set in request headers, and extensively
+  annotated the cookie support code for ease of further development. - FM
+* Added ability to set SHOW_CURSOR in lynx.cfg, to override the compilation
+  setting in userdefs.h, and made the -show_cursor command line switch a
+  toggle for the compilation or configuration default. - FM
+01-18-97
+* Bug fixes and memory leak plugs for the cookie support.  Added ability
+  to delete individual cookies or entire domains via the Cookie Jar Page
+  (Ctrl-K).  The domains and cookies are displayed as DL/DT/DD blocks,
+  with links for each domain and cookies name.  The deletions are done
+  by activating those links, which can be numbered, so it should be OK
+  for blind users. - FM
+* Tweaks of the news/nntp/snews gateway. - FM
+* Tweaks of paragraphing if ADDRESS, BANNER, BLOCKQUOTE, BQ, FN, MARQUEE
+  or NOTE blocks are nested (note that nesting does not yield progressive
+  indentations of these blocks). - FM
+01-16-97
+* Added "first pass" cookie support based on patches from Andrew Kuchling
+  (amk@magnet.com).  Still needs work (see comments at top of LYCookie.c).
+  A SET_COOKIE symbol in userdefs.h and lynx.cfg determines whether cookie
+  support will be on or off by default, and the default can be toggled
+  via a -cookies command line switch.  When on, Set-Cookie headers invoke
+  confirmations with possible replies of 'Y'es or 'N'o for that cookie,
+  'A'lways, to accept all cookies from that domain, or ne'V'er to never
+  accept cookies from that domain.  The Cookie Jar can be examined via
+  the COOKIE_JAR keystroke command, mapped by default to Ctrl-K.  The
+  Cookie Jar, and any 'A'lways or ne'V'er settings, do not presently
+  outlast the Lynx session. - FM
+01-14-97
+* Added use of DEFAULT_INDEX_FILE or the URL from an -index=URL command
+  line switch as the the HREF for a banner LINK with REL="Index" and no
+  HREF of its own (see the 01-01-97 mods and the HTML Banners section of
+  the Lynx Users Guide). - FM
+01-13-97
+* Tweaks of the news gateway. - FM
+* Added "Negotiate: trans" header for GET and HEAD requests.  Shouldn't
+  be necessary to get 300 instead of 406 replies when nothing matches
+  the Accept and Accept-foo request headers, but some HTTP/1.1 servers
+  apparently want it when the UA declares itself as HTTP/1.0, as Lynx
+  still does. - FM
+01-12-97
+* More updates of the online 'h'elp files. - FM
+* Simplified the code for checking whether a startfile is a bookmark file
+  entered as a URL instead of invoked via the -book switch.  The previous
+  code was tripping up some versions of the osf and linux compilers. - FM
+01-10-97
+* Replaced the realloc() in split_line() of GridText.c with a calloc(),
+  memcpy(), FREE() sequence for all systems, not just AIX and ultrix,
+  based on analysis of memory wastage by Hans Reiser
+  (dl9rdz@cip.e-technik.uni-erlangen.de). - FM
+* Tweaks of the body= handling in mailto URLs. - FM
+* Tweaks of the ftp gateway. - FM
+* Restored inheritance when resolving versus a base with the same scheme,
+  because the RFC1808 and Fielding Draft behavior of not doing so yields
+  too many failures in the real world (sigh...). - FM
+01-09-97
+* Ugh!  The distribution zip still had the Nov 4, 1996 HTTCP.c instead of
+  the one I modified on Christmas.  No wonder people were still reporting
+  the wrong messaging with -DNSL_FORK.  The right HTTCP.c is in there
+  now. - FM
+* Mods to resolve the HREFs for LINKs with REV="made" or REV="owner"
+  versus the base (a many, many year old bug finally caught 8-). - FM 
+* Added HTAlert messages about BASE HREF values, Location header values,
+  and Refresh URL values that were not received as absolute URLs.  We
+  still resolve them versus the RequestURI, since that's invariably
+  what is intended, and thus the optimum "error recovery" strategy. - FM
+* Added handling of cc= and body= fields in ?searchpart strings of mailto
+  URLs.  They are described in draft-hoffman-mailto-url-00.txt recently
+  posted to the URI-WG list.  This draft ignores the objections which have
+  been filed about changing the semantics of mailto and breaking clients
+  which are fully conformant with the mailto specs in RFC1738, instead of
+  using a new scheme name (e.g., smtp:) for URLs with mail headers, and it
+  extends the ill-advised use of '&' as puctuation in URLs instead of
+  honoring the previous IETF effort to seek it's replacement by ';' as the
+  URL name=value separator and, in effect, treating them as parameters
+  without need to worry about confusions with entities when the URLs are
+  attribute values in text/html.  However, the chairman of the URI-WG is
+  a co-author of this draft, so, sigh...  As far as this Lynx code is
+  concerned, the mods are more "error recovery" to cope with the sad things
+  which have afflicted the Web during the past 2-3 years, and use of a
+  ?searchpart in mailto URLs is still DISadvised.  Lynx uses only subject=,
+  cc=, and body= fields from a ?searchpart, using it's own "safe" rules for
+  other mail headers, and ignoring ones other than those three in the
+  ?searchpart as "unsafe".  The cc= values in a ?searchpart are added to
+  the primary address as a comma-separated list for the mail agent, and
+  Lynx's own Cc: is that entered, optionally, by the user.  Any body= field
+  is passed to the external editor, if one has been defined, for review and
+  possible modification.  Otherwise, it is scrolled for review.  The mailing
+  can be cancelled at any time (via Ctrl-G), and via a statusline prompt
+  after everything has been reviewed, if the user judges the body and/or
+  addresses to be unsafe or inappropriate. - FM
+* Moved information and prompt strings in LYMail.c to installer-modifiable
+  symbols in LYMessages_en.h. - FM
+01-07-97
+* Eliminated forced exits for keyboard input buffer overruns on VMS.
+  There's no perfect way to deal with it, but Lynx should recover
+  gracefully most of the time now, and do nothing bad if ungraceful. - FM
+* Added handling of Content-Base and Content-Location MIME headers when
+  'd'ownloading, 'p'rinting, or mailing HTML source.  For this, as
+  for rendered HTML streams (see 01-06-97 mods) the base is determined
+  according to HTTP/1.1 rules:  If a Content-Base header was received,
+  that's the base.  Otherwise, if a Content-Location header was received
+  and it's an absolute URL, that's the base.  Otherwise, the URL used
+  to retrieve the document is the base.  When actually rendering, any
+  BASE tag in the document overrides the base derived from headers.
+  When 'd'ownloading, or outputting HTML source for a 'p'rint option,
+  an X-URL comment with the URL used to retrieve the document and a
+  BASE tag with the header or URL-derived base are inserted at the top
+  of the document.  These should be moved down into the actual HEAD
+  section to make the HTML fully legal, but will work as is if the
+  output is used in conjunction with automatic invocation of Lynx or
+  Netscape as a text/html helper application.  When mailing with an
+  SMTP-conformant mailer, the actual URL used to retrieve the document
+  is indicated via an X-URL header, and for HTML source, a Content-Base
+  and a Content-Location header are included, set to what was actually
+  received by Lynx via MIME headers, or to the retrieval URL. - FM
+01-06-97
+* More updates of the online 'h'elp.  The Visited Links Page ('V'),
+  multi-bookmark file support, REL/REV and META enhancements, and new
+  switches are now all fully documented in the 'h'elp. - FM
+* Added handling of Content-Base and Content-Location MIME headers for
+  rendered HTML streams (still using the document's URL in the 'd'ownload
+  and 'p'rint (and mailing) BASE prepending kludge). - FM
+* Added code to avoid getting tripped up by double-quoted header values
+  in HTMIME.c.  We still need more sophisticated parsing of possibly
+  compound HTTP/1.1 headers, but we don't yet use any of those. - FM
+* Tweak of the efficiency mods for command line parsing in LYMain.c. - FM
+* Simplified some code in LYMainLoop.c that was tripping up the AIX32
+  compiler. - FM
+01-04-97
+* More updates of the online 'h'elp. - FM
+* Added DIRED_MENU support for .tgz files as for .tar.gz files. - FM
+01-03-97
+* Made the command line parsing in LYMain.c more efficient. - FM
+* Added -nopause switch for setting InfoSecs, MessageSecs, and AlertSecs
+  to zero.  Can be used to eliminate forced statusline pauses during
+  traversals. - FM
+* Mods to allow absolute zero quality values for Accept headers, so that
+  in mailcap files users can do things like map image/* to a helper app
+  but exclude particular image subtypes which the app can't handle by
+  assigning q=0 for that subtype.  HTTP/1.1 still specifies 4 significant
+  figures for quality values, so if the value is non-zero, Lynx still
+  forces a minimum of q=0.001. - FM
+* Typo fixes in lynx.cfg. - LWV
+01-02-97
+* Updates of the online 'h'elp files. - FM
+* Made the parsing of lynx.cfg in LYReadCFG.c more efficient. - FM
+01-01-97 -- Happy New Year!
+* More partial/relative HREF resolving enhancements.  Everything is now
+  handled as recommended in Larry Masinter's -03 revision of Roy Fielding's
+  -02 URL ID, except file and ftp URLs (which Lynx handles as described
+  in the online 'h'elp ).  Note, though, that Lynx handles known schemes
+  on a scheme-by-scheme basis, and for schemes that involve substitutions
+  of "/" for a NULL/zero-length path, Lynx inserts the "/" at the resolving
+  stage, so those slashes are present where the Fielding test suite doesn't
+  indicate them, but the actual requests sent to servers (or bad URL message
+  if it's a scheme that requires a host field and doesn't have a default)
+  will be the same.  Note, also, that Lynx sends only the  path<?searchpart>
+  ("absolute path") in it's direct http requests and indicates the host of
+  the URL in the Host:  header, i.e., sends the absolute URL only to proxies.
+  Note, as well, that Lynx treats a zero-length attribute value for an HREF,
+  SRC, etc. as a reference to the currently displayed document, but still
+  uses the base (which might not be the current document's address) as the
+  default for FORMs without an ACTION specified, or ISINDEX tags without
+  an HREF or ACTION specified. - FM
+* Expanded REL/REV handling.  All of the REL values in the (expired) Maloney
+  and Quin draft-ietf-relrev-00.txt ID which make sense for banner links in
+  Lynx have been added.  For REL="Help" without an HREF in the LINK, Lynx
+  uses its helpfile URL.  For REL="Home" without an HREF in the LINK, it
+  uses the configuration startfile or WWW_HOME URL (i.e., not a startfile
+  specified on the command line), or the command line homepage, if it was
+  specified. - FM
+* Added handling of fragments in conjunction with URL expansion guessing for
+  startfile, homepage and 'g'oto strings.  Note that any '#' that is not a
+  fragment delimiter should be hex escaped (%23), and ideally all reserved
+  or unsafe characters will be hex escaped in the user-entered string, though
+  you can get away with not using the hex codes for most others, depending on
+  their positions in the string.  Also note that on VMS if you include the
+  version for local files it must precede the fragment (e.g., foo.html;3#frag)
+  as for parameters. - FM
+12-26-96
+* Mods of HREF resolving to be more consistent with the latest IETF draft
+  (http://www.ics.uci.edu/pub/ietf/uri/draft-fielding-url-syntax-02.txt).
+  Most importantly, lone fragments (HREF="#fragment") are resolved versus
+  the current document's URL, and no longer versus the BASE, if present.
+  There are a few things in the draft which are at odds with what virtually
+  all currently deployed browsers do, and so I stuck with the "deployed"
+  behavior.  Try the tests in  http://www.ics.uci.edu/~fielding/url/  to
+  see where Lynx still differs from the draft. - FM
+* Tweaks of 'z'ap handling. - FM
+12-24-96
+* Tweaks of DIRED_SUPPORT and make for osf. - FM
+12-23-96
+* Added code to check if the startfile has BOOKMARK_TITLE as its title,
+  and if so, and it's in the bookmark file list, add the bookmark element
+  and reload to have it treated as if it were invoked with -book. - FM
+12-21-96
+* Added code for the DIRED_MENU command ('f' and 'F' by default) to invoke
+  CSwing on VMS if CSWING_PATH is defined, as explained in userdefs.h and
+  lynx.cfg . - FM
+12-20-96
+* More improvements in the fatal error and memory exhaustion handling, and
+  plugging of memory leaks. - FM
+* Changed "newline" to "Newline" in LYMainLoop.c to deal with another
+  reported, ill-advised, macro in the AIX 4.2 curses.h. - FM
+* More tweaks of lynx.cfg. - FM
+12-19-96
+* Improvements in the messaging and cleanups for aborts on fatal errors
+  and exits on memory exhaustion. - FM
+* Worked v2.1 of lpansi.c into the distribution. - FM
+* Modified lynx.cfg to reflect the compilation defaults consistently, and
+  changed the compilation default for SUBSTITUTE_UNDERSCORES to FALSE. - FM
+* Changed the "lines" element to "Lines" in the HText structure and the
+  "tab" structure name to "Tab" to cope with some unwise employee reportedly
+  using all lower case "lines" and "tab" strings as macros in the AIX 4.2
+  curses.h. - FM
+12-17-96
+* Restored use of the -l format in the parent links of local Unix directory
+  listings if LONG_LIST is defined, without the v2.6 bug of creating strange,
+  trailing relative or escaped strings.  As far as I can tell from exercising
+  them, the DIRED_SUPPORT and LONG_LIST handling are now fully debugged
+  (famous last words...  8-). - FM
+12-16-96
+* Don't reiterate parent links in local directory listings.  They are
+  offered only in the top, up to parent link if NO_PARENT_DIR_REFERENCE
+  is not defined. - FM
+* Moved more HTML.c functions to LYCharUtils.c. - FM
+* Tweak of META handling, which was causing crashes (due to freeing an
+  anchor structure prematurely in the 12-13-96 mods for moving HTML.c
+  code to LYCharUtils.c). - FM
+* Block Unix relative path strings in lynxexec and lynxprog URLs. - DT
+12-14-96
+* Added a COLLAPSE_BR_TAGS compilation and configuration symbol for
+  determining whether Lynx collapses serial BR tags.  Note that the
+  valid way to create extra blank lines in HTML is with PRE blocks that
+  contain only newlines. - FM
+* Fixed a longstanding glitch in the alignment handling which could
+  cause a Paragraph's ALIGN value to cross embedded blocks, rather than
+  restoring the appropriate alignment for the outer division or block
+  on close of the embedded block. - FM 
+* Modified HR handling so that it inserts the same before and after
+  spacing regardless of whether P end and/or start tags are present
+  before and/or after the HR. - FM
+* Don't insert the bookmark file description and filepath if multiple
+  bookmark file support has been turned off, and this is the default
+  bookmark file (but they will still be inserted if it's not the default,
+  e.g., if it's another bookmark file viewed before the support was
+  turned off, and retrieved as a previous document). - FM
+12-13-96
+* Added parsing of Content-Disposition in META tags and setting the
+  suggested file name if  file; filename=name.suffix  is in the value
+  of the Content attribute and we don't already have that via a server
+  header. - FM
+* Incorporated almost all globals related to stream parsing and page
+  display in HTML.c and GridText.c into the HTML object structure and
+  HText structure to make the parsing and display functions more nearly
+  re-entrant, and moved several functions from HTML.c to LYCharUtils.c
+  to reduce the size of HTML.c. - FM
+* Added -cckr to the libwww Makefile compiler options for SGI. - Carl
+  Buxbaum (crb@world.std.com)
+* Fixed typo in LYMainLoop.c that affected the 'd'ownload command when
+  DIRED_SUPPORT is enabled. - FM
+12-10-96
+* Implemented Safe header handling and prompting about resubmissions of
+  forms with method POST along the lines described in the 24-Nov-96 IETF
+  ID: http://gewis.win.tue.nl/~koen/draft-holtman-http-safe-01.txt
+  Lynx prompts for confirmation whenever it detects that a resubmission
+  would occur, unless the previous reply included "Safe: yes".  Prompts
+  always will occur if the -resubmit_post toggle is on (since resubmission
+  always would occur; not advised).  If not toggled on, resubmissions
+  would occur when no_cache is set or the previous reply has been dumped
+  from the cache.  When using the PREV_DOC command or History Page, if
+  confirmation is not obtained, Lynx will skip to the yet earlier document,
+  or cancel, as appropriate. - FM
+* Added parsing of the Safe header in HTMIME.c, and added a safe element
+  to the anchor and document structures.  Will be FALSE unless a Safe
+  header is received that specifies "YES" or "TRUE" (case-insensitive,
+  only "YES" is in the specs), and applies only to replies from form
+  submissions with the POST method. - FM
+* Cleanup of code in HTAccess.c.  May correct problem of crashes for
+  ISINDEX searches on some systems, though I couldn't reproduce that
+  problem here. - FM
+12-09-96
+* Added an HTSetPresentation() for image/x-xbitmap in HTInit.c when DISPLAY
+  is set. - FM
+* Added an LYOutOfMemory boolean that is set by the outofmem() macro, and
+  code in the Unix FatalProblem() and VMS exit handler for reporting the
+  memory exhaustion instead of the misleading "bug" message when they are
+  invoked due to memory exhaustion.  May not be reported reliably for
+  linux, because for some reason I don't understand, the SIGBUS trapping
+  is ifdef'ed out for linux in LYMain.c. - FM
+* Fixed typo in the new LYAddVisitedLink() in LYHistory.c of yesterday's
+  mods. - KW
+12-08-96
+* Added a VLINKS command, mapped by default to upper case 'V', and code
+  for creating a list of all links 'V'isited during the current Lynx session
+  in order of recency (most recent highest in the list).  Lower case 'v' is
+  still mapped to VIEW_BOOKMARKS.  The VLINKS listing is complementary to
+  the History Page listing, and formatted similarly.  It excludes POST
+  replies, and bookmark, menu and list files (use the History Page or
+  direct keystroke commands for those).  It includes any links that were
+  downloaded, or passed to a helper app (except mailto and newsreply or
+  newsfollowup links, since those require activation in the original
+  document for proper inclusion of it in the email message or news
+  post).  You can print the Visited Links Page, or 'd'ownload it via
+  the History Page. - FM
+* Added reporting of the Charset parameter, if present in a server reply
+  header, META tag, or by virtue of a suffix map, to the showinfo ('=')
+  display. - FM
+12-07-96
+* Added 'p'rint menu support for the History Page. - FM
+* Added a content_length element to the anchor structure and use that,
+  if a Content-Length header has been received, to indicate the total
+  bytes in the statusline when receiving the stream. - FM
+* Include HTTP_ACCEPT_LANGUAGE in the lynxcgi environment. - David Trueman
+  (david@cs.dal.ca).
+12-06-96
+* Many more cleanups and commenting of the code for the benefit of new
+  developers. - FM
+* Tweaks of URL parsing and path simplifications.  Added simplification
+  of the file://localhost paths from startup and 'g'oto guesses. - FM
+* More anti-crash protections for bad HTML in SELECT blocks. - FM
+* Usability enhancement for DIRED's 'F' menu: list number and names of
+  (some of) the tagged items, and provide a way to untag all items. - KW
+* Force screen refresh after a DIRED system command has failed. - KW
+* Modified HTFile.c to handle relative and "Up to parent" links more
+  effectively. - KW
+* Added KEYGEN to the DTD (but no code to do anything with it yet). - FM
+12-05-96
+* Fixed typo in the for-Unix section of LYAddPathToHome() that was added
+  yesterday in LYUtils.c. - James Troup (J.J.Troup@comp.brad.ac.uk)
+12-04-96
+* Numerous cleanups and commenting of the LYfoo.c and LYfoo.h modules,
+  for the benefit of new Lynx developers. - FM
+* More security-related enhancements and polishing up of the multiple
+  bookmark file support. - FM
+* Increased the sizes of MAXHIST and MAXLINKS, added statusline messages
+  should they ever be exceeded (not likely now 8-), and code for freeing
+  all excess pointers on each page draw instead of letting them grow and
+  freeing them on exit (should help for memory-limited systems 8-). - FM
+* Tweaks of DIRED_SUPPORT. - KW
+12-02-96
+* Show nntp server status messages in group listings when not 221 (normal
+  reply to HEAD request), so the user will know that the articles are
+  not available from the server, rather than a bug in Lynx. - FM
+* Tweaks of BASE resolving. - FM
+* Added "trick" to send hostname guesses to stdout when the startfile or
+  homepage are not URLs, as we send to the statusline for 'g'oto guesses
+  (but don't use stdout if we are not interactive and the desired output
+  is going to stdout).  If the DNS lookup stalls, one thus can Control-C
+  out, instead of wondering why Lynx is taking so long to start up. - FM
+* Cleaned up the read_rc() and save_rc() functions in LYrcFile.c. - FM
+* Eliminated all printw() calls to avoid problems with non-ASCII and/or
+  multibyte/CJK characters. - FM
+* Numerous additional bug fixes and enhancements of the multiple bookmark
+  file support. - FM
+* Got rid of the ADVANCED_MULTI_BOOKMARKS symbol now that the choice can
+  be made in the 'o'ptions menu and saved in the .lynxrc file. - FM
+11-30-96
+* Added the ability to set the advanced mode for multiple bookmarks from
+  the options menu and save the defaults in the .lynxrc file - HL
+* Various typo corrections including one which kept LYMainLoop.c from
+  compiling under Unix when DIRED_SUPPORT was defined. - HL
+11-29-96
+* Numerous additional refinements and enhancements of the multiple bookmark
+  support.  Added support for REFRESH and PREV_DOC in the options and bookmark
+  menus, and NEXT_PAGE, PREV_PAGE, and ACTIVATE in the bookmark menus or
+  prompts.  Expanded the anchor and document structures to keep track of
+  different bookmark files in conjunction with VIEW_BOOKMARK, ADD_BOOKMARK,
+  and DEL_BOOKMARK commands, to restore the proper bookmark files on reloads
+  (overt, or because the cache was dumped for subsequent documents accessed
+  via bookmark links), and in conjunction with security-related restrictions.
+  Multiple bookmark support can be regulated via MULTI_BOOKMARK_SUPPORT,
+  BLOCK_MULTI_BOOKMARKS and ADVANCED_MULTI_BOOKMARKS symbols in userdefs.h
+  (or as SITE_DEFS in the Makefile) and lynx.cfg.  The multiple bookmark
+  support can be blocked via a -restrictions=multibook command line switch,
+  which is also set for -anonymous and -validate.  Prompting or display of
+  the bookmark file selection menu occurs only if bookmark files in addition
+  to the startup default have been defined (via the B)ookmark command in the
+  'o'ptions menu, if mu(L)ti bookmarks has been turned on; the setting and
+  definitions can be saved in the .lynxrc file).  Plugged memory leaks in
+  the previous implementation of multiple bookmark support.  Added code for
+  inserting the current description and filepath for each bookmark file
+  dynamically during rendering. - FM
+* Another tweak of attribute order in HTMLDTD.c. - KW
+11-28-96
+* Tweaked multiple bookmark support to fix an error which was causing a
+  crash on some systems and incorrect behavior on others - HL
+* Tweaked editing of multiple bookmark filenames to correct shifting of 
+  screen between multiple pages - HL
+11-26-96
+* Added support for setting the rendering of SELECT OPTIONs as popup menus
+  versus radio button lists via the 'o'ptions menu, and saving the default
+  in the RC file.  Changed NO_SELECT_POPUPS to USE_SELECT_POPUPS in lynx.cfg
+  and userdefs.h.  The -popup switch still overrides everything. - FM
+* Added multiple bookmark support along the lines of the patch from Filip M.
+  Gieszczykiewicz (filipg@paranoia.com), plus numerous enhancements of the
+  'o'ptions menu and bookmark handling. - FM
+* Tweaks of attribute orders in HTMLDTD.h and HTMLDTD.c. - KW
+11-25-96
+* Updated the "Lynx Enhanced Pages" links to the new "Lynx links"
+  (http://www.crl.com/~subir/lynx.html) throughout the help, docs,
+  and code. - FM 
+11-24-96
+* Modified the ENCTYPE="multipart/form-data" handling to indicate the
+  Content-Type with charset parameter, when known, within each part
+  rather than in the main Content-Type header. - FM
+* Corrected typo in HTNews.c. - FM
+* Added support for setting the suggested filename in 'd'ownload and
+  'p'rint options based on the Content-Disposition header if it included
+  the string  file; filename=name.suffix  in its value.  Can be used by
+  CGI scripts to set the suggested filename for saves to disk, downloads
+  or mailings of the script's reply body, so it won't be the last symbolic
+  element in the path field of the form's ACTION (which is normally the
+  the script, itself, or a PATH_INFO element, and thus misleading). - FM 
+* Tweaks of change_sug_filename() in LYUtils.c for better handling of
+  gzipped files on VMS. - FM
+11-23-96
+* Added reporting of the Server, Date and Last-Modified headers, if present
+  in server replies, to the showinfo ('=') display. - FM
+* Added the ability to store the NO_SELECT_POPUPS in the .lynxrc, but the
+  .lynxrc must be edited manually until the options handling is converted
+  to a form-like interface that accommodates more options.  For now, select
+  'O'ptions and write out the options with '>' to create a block in .lynxrc
+  with an explanation of the switch.  The switch is "select_popups" and
+  can have the values of "on", "off", or nothing.  If nothing, the default
+  set in userdefs.h or lynx.cfg will persist.  Otherwise, "on" will set use
+  of popups and "off" will set use of radio buttons as the default.  The
+  startup default always can be toggled via the -popup switch. - HL & FM
+* Corrected a couple of typos in the help files. - HL
+11-22-96
+* Added support for WHEREIS ('/') and 'n'ext searches within SELECT popups.
+  The buffering for 'n'ext is separate from that in the main loop (i.e.,
+  for non-form field document searches), but all previously entered search
+  strings are still combined into a circular buffer and can be accessed via
+  the up-arrow or down-arrow keys at the prompt for a search string.  The
+  searches within popup menus do not yield highlighting of the search string,
+  but simply positioning of the cursor on successive options which contain
+  the search string. - FM
+* Added support for all of the navigation commands within SELECT popup
+  windows, including HOME, END, UP_TWO, DOWN_TWO, UP_HALF and DOWN_HALF,
+  in addition to the single line and paging navigation commands. - FM
+* Added support for the REFRESH command within SELECT popup windows. - FM
+* Tweak of hookless snews handling. - FM
+11-21-96
+* Added handling of forms with ENCTYPE="multipart/form-data".  Note that
+  we still don't support INPUTs with TYPE="file" or TYPE="range", and
+  thus still set the DISABLED attribute for all fields in the form if
+  either of those two TYPEs are present in it. - FM
+* Tweak of -mime_header handling. - FM
+* Typo fixes of comments in HTML.c. - Albert S Woodhull
+  (aswNS@hamp.hampshire.edu)
+11-20-96
+* Added a NO_SELECT_POPUPS compilation (userdefs.h) and configuration
+  (lynx.cfg) definition, normally set FALSE.  If set TRUE, single-choice
+  SELECT blocks (i.e., ones without the MULTIPLE attribute) will be handled
+  as a list of radio buttons instead of via a popup window.  Also added a
+  -popup command line switch for toggling the compilation or configuration
+  setting. - FM
+11-18-96
+* Tweak of LYFindEndOfComment() in LYCharUtils.c. - Brian Borowski
+  (brianb@braille.uwo.ca)
+11-17-96
+* Added links to the lynx-dev hypertext archive at FLORA in the online
+  'h'elp. - FM
+* Tweaks of my_spawn() in LYLocal.c. - KW
+11-16-96
+* Added support for use of the 'd'ownload command on TYPE="submit" and
+  TYPE="image" submit buttons.  You still must use the History Page for
+  TYPE="text" INPUT fields that also act as submit buttons by virtue of
+  being the only non-hidden field, because the 'd'ownload command key
+  could be a text entry into the field, and thus must be treated as
+  such. - FM 
+11-15-96
+* Mods of HTFormat.c and HTTP.c for better handling of unexpected server
+  disconnects. - FM
+11-13-96
+* Wind down the element stack on EOF if any unclosed tags were received. - FM
+* Fixed typos in the HTMLDTD.c BODYTEXT definitions. - FM
+11-10-96
+* More tweaks of hook-less snews handling. - FM
+* Changed the default STARTFILE to http://lynx.browser.org/ and the default
+  HELPFILE to the v2.6 set at NYU in userdefs.h and lynx.cfg. - FM
+* New function HTUnEscapeSome() in HTParse.c for unescaping selected
+  characters in a string.. - KW
+* Numerous changes to make DIRED_SUPPORT work as intended, to use the
+  library's HTList functions and macros for managing the list of tagged
+  file URLs, and to keep track of proper levels of URL escaping so that
+  unusual filenames which contain #% etc. are handled properly.  Can now
+  edit, move, etc. Abc%25252525def.html, #xy#~, etc. - KW
+11-09-96
+* Treat 301 or 302 redirection of a POST as 303 when the Lynx process is
+  non-interactive, rather than rejecting the redirection, since 303 is
+  still most likely what the CGI script actually intends (will still
+  prompt if the process is interactive). - FM
+* Added parsing and trace mode reporting of Content-Disposition headers
+  in HTMIME.c (should be used, someday, to set the suggested file name
+  for disk saves and downloads based on any filename=foo.blah field). - FM
+* Further mods of HTNews.c to facilitate use of Lynx without SSL-hooks
+  in conjunction with an SSL-capable daemon/proxy for snews URLs that
+  returns NNTP streams for Lynx itself to convert into HTML, instead
+  of already converted streams as from a standard proxy. - TZ & FM
+11-08-96
+* Changed information returned by "-version" in LYMain.c to point to
+  lynx.browser.org and added a date to the copyright info. - HL
+11-07-96
+* Mods of HTNews.c to facilitate use of Lynx without SSL-hooks in
+  conjunction with an SSL-capable daemon/proxy for snews URLs. - TZ
+11-05-96
+* Typo fixes in HTMIME.c. - KW
+* Tweak of NSL_FORK mods. - FM
+11-04-96
+* Tweaks of host parsing when a password and/or username is present
+  in override_proxy() of HTAccess.c. - FM
+* Tweaks of the UNDERSCORES and STARS macro setup and usage to avoid
+  possible crashes for FORMs with long values. - FM
+* Worked in Tom Zerucha's (tz@execpc.com) code for fork-based name
+  server lookups that can be 'z'apped.  May not yet be portable to
+  all flavors of Unix.  Add -DNSL_FORK to your SITE_LYDEFS to try
+  it. - FM
+11-02-96
+* Fixed typo in HTAlert.h. - FM
+* Cleaned up HTTCP.c code, simplified some of its spaghetti
+  ifdef'ing, and worked in mods to bypass connection confirmations
+  when Lynx is SOCKSified and the socks_flag is set. - FM
+* Added recognition and acceptance of text/x-sgml and text/sgml
+  MIME types (all that I've encountered thus far work fine with
+  Lynx, though it doesn't yet interpret marked sections). - FM
+* Added socket function prototypes for MultiNet in tcp.h. - FM
+* Mods to facilitate application of the SSL patches (after some
+  corrections in the patches to keep HTLoadHTTP re-entrant, make
+  CONNECT work as intended again, and eliminate memory leaks in
+  the SSLeay adaption) - FM
+* Adding info about -DNO_TTYTYPE in top level Makefile. - FM
+* Use clrtoeol() in LYOptions.c to ensure that no terminals which use
+  reverse video for standout() will have trailing reverse fields on
+  edits of option values. - DK
+* Offer user@host instead of WebMaster@host for the 'c'omment command
+  if the path for the URL begins with a tilde and there is no
+  LINK REV="made" present. - FM
+* Tweaks of inews Makefile and clientlib.c. - Christopher R. Maden
+  (crm@ebt.com)
+* Check nhist before attempting a DIRED_SUPPORT directory listing in
+  LYShowInfo.c. - KW
+10-21-96
+* Offer WebMaster@host for the 'c'omment command if no LINK REV="made"
+  was present in a text/html document, and save a known owner URL when
+  toggling to source ('\') so that the 'c'omment command can still be
+  used with that owner's (mailto or homepage) URL, but the source can
+  be included in the comment, as would be desirable (instead of a bad
+  rendering) when sending a comment about bad HTML in the document. - FM
+10-20-96
+* Added code for traversing the pseudo-documents created for client-side
+  image MAPs.  See the updated CRAWL.announce for more information. - FM
+10-19-96
+* Added definitions in LYCurses.h relating curses function calls to slang
+  functions or emulations for compatibility with new versions of slang,
+  based on patch from John E. Davis (davis@space.mit.edu). - FM
+* Added unescaping of the full address fields in mailto URLs or ACTIONs,
+  and improved the reliability of the parsing of the subject header from
+  the ?searchpart Netscapism when present. - FM
+* Give user option to use 303-like conversion of POST to GET in confirmation
+  requests for redirection of POSTs, base on patches from Drazen Kacar
+  (dave@fly.cc.fer.hr). - FM
+* Tweaks of POST content submissions in HTTP.c, based on patch from
+  KW. - FM
+* Fixed EOF checks in HTAAFile.c, HTGroup.c and HTPasswd.c, and improved
+  host address parsing in HTTCP.c, based on patches from Larry Schwimmer
+  (schwim@cyclone.stanford.edu) and Klaus Weide (kweide@tezcat.com). - FM
+* Added targets for umaxv and umaxv-slang for Encore's UMAXV - Thanh Ma
+  (tma@encore.com)
+10-16-96
+* Send the rendering of decompressed files to stdout with -dump, don't
+  spawn a viewer under any circumstances if -dump was used instead of
+  -source for Content-Types that are not text/html, and remove the
+  temporary decompressed files before exiting with -dump or -source. - FM
+* Properly handle TYPE="radio" versus TYPE="checkbox" INPUTs with NULL
+  or zero-length VALUEs. - FM
+* Added a continuation line token for the netbsd-ncurses target - HL
+* Fixed a typo in HTMIME.c in the trace output - HL
+* Block predictable buffer overrun in GridText.c if a page has more
+  than MAXLINKS links in it. - FM
+10-01-96
+* Add a Mime-Version header to the other headers in LYPrint.c so that the
+  09-20-96 mods for mailing source do what they were intended to do. :) -
+  Hamish MacEwan (macewanh@diatp.dia.govt.nz)
+09-20-96
+* Add a BASE tag to the tops of HTML source files, a la Netscape, when
+  mailing or downloading, and don't worry, for now, if that creates
+  technically invalid HTML (since Lynx copes with it as of the 09-15-96
+  mods 8-). - FM
+* Include Content-Type, Content-Location and Content-Base headers when
+  mailing HTML source on Unix. - FM
+* Use .txt versus .html suffixes when submitting rendered versus HTML source
+  temporary files to VMS MAIL, so that transports such as PMDF will indicate
+  the appropriate Content-Type. - FM
+09-17-96
+* Handle illegally positioned BASE tags. - FM
+* Tweak of Q nesting level checks. - Pawel Wiecek
+  (coven@i17linuxb.ists.pwr.wroc.pl)
+* Fixed typo in HTMIME.c for parsing of Pragma header. - Wilson Cheung
+  (wcheung@netcom.com)
+* Added parsing of Set-Cookie header in HTMIME.c (see IETF ID
+  http://www.ics.uci.edu/pub/ietf/http/draft-ietf-http-state-mgmt-03.txt
+  for info on how to implement it's use). - FM
+* Fixed typo in LYMainLoop.c for display of error message when up arrow is
+  pressed at the top of a document. - Hiram Lester, Jr. (hwlester@pobox.com)
+09-16-96
+* Use standard ls -l parsing of LIST output for Windows_NT ftp servers in
+  Lynx v2.6 as in v2.5. - FM
+
